• Capture VHS to Mac

  - by Kato

  I have a Mac Pro running Leopard and a RCA to USB cable and a VCR. I'm trying to figure out the best way to capture VHS tapes onto my computer using what I have. I cannot seem to find video capturing software for Macs that would do this through USB, especially for cheap or free, or with the ability to capture in MPEG2 format. Does anyone have directions/suggestions?

• ALSA samples capture: cannot open device

  - by Randagio

  I'm quite new to Linux (Lubuntu 12.04 for sake of precision) and ALSA programming at all. I'm trying to write a C program to capture audio from internal PC microphone for processing it. So as first step I google a bit and I found this article for capturing audio samples A tutorial on using the ALSA Audio API but when I compile it and execute it with: ./capture "default" or ./capture "hw:0,0" and all the possible variants on theme it always raises the error: cannot open device hw:0,0 (no such file or directory). So the issue is: what is the name of the mic audio device to pass as parameter to record the audio from mic ? The mic is working ok because the Sound Recorder program records sounds perfectly and I can playback them. The output of the aplay -l is the following : **** List of PLAYBACK Hardware Devices **** card 0: I82801DBICH4 [Intel 82801DB-ICH4], device 0: Intel ICH [Intel 82801DB-ICH4] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: I82801DBICH4 [Intel 82801DB-ICH4], device 4: Intel ICH - IEC958 [Intel 82801DB-ICH4 - IEC958] Subdevices: 1/1 Subdevice #0: subdevice #0 and this is the amixer output (cut) Simple mixer control 'Master',0 Capabilities: pvolume pswitch penum Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 31 [100%] [0.00dB] [on] Front Right: Playback 31 [100%] [0.00dB] [on] Simple mixer control 'Master Mono',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined penum Playback channels: Mono Limits: Playback 0 - 31 Mono: Playback 4 [13%] [-40.50dB] [on] Simple mixer control 'PCM',0 Capabilities: pvolume pswitch penum Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 31 [100%] [12.00dB] [on] Front Right: Playback 31 [100%] [12.00dB] [on] Simple mixer control 'CD',0 Capabilities: pvolume pswitch cswitch cswitch-exclusive penum Capture exclusive group: 0 Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: Playback 0 - 31 Front Left: Playback 0 [0%] [-34.50dB] [off] Capture [off] Front Right: Playback 0 [0%] [-34.50dB] [off] Capture [off] Simple mixer control 'Mic',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined cswitch cswitch-exclusive penum Capture exclusive group: 0 Playback channels: Mono Capture channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Playback 22 [71%] [-1.50dB] [on] Front Left: Capture [on] Front Right: Capture [on] Simple mixer control 'Mic Boost (+20dB)',0 Capabilities: pswitch pswitch-joined penum Playback channels: Mono Mono: Playback [off] Simple mixer control 'Mic Select',0 Capabilities: enum Items: 'Mic1' 'Mic2' Item0: 'Mic1' Simple mixer control 'Stereo Mic',0 Capabilities: pswitch pswitch-joined penum Playback channels: Mono Mono: Playback [off] so for aplay it seems I have no recording device, but for amixer I've got the mic, a mic boost and mic stereo as well with all those gorgeous stuffs on their place !!. If so, how could my Sound Recorder record the audio without any problem at all ?!?! For sure I'm giving the wrong device name to the command line for capturing audio but I'm loosing the hope for finding the correct one ! Please help....before I tear my hair out !!!

• Purple start screen - no splash screen

  - by Peter

  After installing Ubuntu 11.10 on a new computer everything worked fine for a few weeks and now suddenly when starting up Ubuntu I get a blank purple screen with no "ubuntu" splash and the 5 dots but the system does start up. What has happened to loose the ubuntu splash screen? Also, I've checked in the grub startup and it has "quiet splash" in the linux line. I have an ATI radeon 5450 graphics card which needed nomodeset to be added to the grub line when booting for the first time off the install CD but now this line has disappeared from the grub startup. Can anyone help. Thanks

• screen DPI - is there and equivalent command/action to Windows 150% Display

  - by Yekhezkel Yovel

  I have a wide screen of high resolution and I see everything small on it. So In windows I set the display to 150%, I would like to do something similar in Ubuntu. Simply changing screen resolution to lower resolution doesn't help because Ubuntu is in a virtual machine and it simply changes the VM window to the actual resolution. Is there a command or a simple hack that can do the trick? EDIT: I am running Ubuntu as a VirtualBox VM on Windows 7 host.

• State / Screen management in Entity Component Systems

  - by David Lively

  My entity/component system is happily humming along and, despite some performance concerns I initially had, everything is working fine. However, I've realized that I missed a crucial point when starting this thing: how do you handle different screens? At the moment, I have a GameManager class which owns a component manager and entity manager. When I create an entity, the entity manager assigns it an ID and makes sure it's tracked. When I modify the components that are assigned to an entity. an UpdateEntity method is called, which alerts each of the systems that they may need to add or remove the entity from their respective entity lists. A problem with this is that the collection of entities operated on by each system is determined solely by the individual Systems, typically based on a "required component" filter. (An entity has to have a Renderable component to be rendered, for instance.) In this situation, I can't just keep collections of entities per screen and only Update/Draw those collections. They'd have to either be added and removed depending on their applicability to the current screen, which would cause their associated components to be removed, or enable/disable entities in a group per screen to hide what's not supposed to be visible. These approaches seem like really, really crappy kludges. What's a good way to handle this? A pretty straightforward way that comes to mind is to create a separate GameManager (which in my implementation owns all of the systems, entities, etc.) per screen, which means that everything outside of the device context would be duplicated. That's bothersome because some things are always visible, or I might want to continue to display the game under a translucent menu window. Another option would be to add a "layer" key to the GameManager class, which could be checked against a displayable layer stack held by the game manager. *System.Draw() would be called for each active layer, in the required order as determined by the stack. When the systems request an iterator for their respective entity collections, it would be pre-filtered to a (cached) set of those entities that participate in the active layer. Those collections could be updated from the same UpdateEntity event that's already used to maintain each system's entity collections. Still, kinda feels like a hack. If I've coded myself into a corner, feel free to throw tomatoes as long as they're labeled with a helpful suggestion. Hooray for learning curves.

• How can I change the default screen resolution?

  - by TheWackerly

  Here's the scoop: I have a crappy VisionQuest TV that I am currently using as a monitor on my computer running XBMCbuntu. It defaults to 1280x768 which the TV will not display correctly. It appears to be the correct size, but the screen is panned WAY to the left. The TV works fine on 1024x768 with the screen sitting in the right spot. Problem is, I have to change the resolution to 1024x768 every time I boot up. Any ideas?

• xubuntu app menu on wrong side of screen

  - by D0X

  I am using Xubuntu 12.04, with a dual monitor setup (with the nvidia driver xinerama enabled). The top panel is spanned acros the two monitors. This works quite fine, except for one thing. When I click the little Application Menu button on my left screen, the application menu opens on the top right corner of the left screen. This is quite annoying, I fiddled in the panel prefs but could not fix this. Any thoughts?

• Starting one BlackBerry screen from another.

  - by DanG

  I've recently run into a snag while putting on the finishing touches for my BlackBerry app. I'm building a login screen which, if the user is successful in logging in, goes to a data loading screen, and then to a home screen. From the home screen, you can use the app. Everything works great but one thing, I can't seamlessly move from the login screen to the loading screen, to the home screen. I can move from the login screen to the loading screen ok, because I'm doing that via a button click which is on the GUI thread, but then I have the login screen at the bottom of the stack and can't get it out using the dismiss method. Once in the loading screen, I can't push the home screen because I'm not doing it via the gui method, though I'm able to update the GUI via the following piece of code: private void checkData(){ Timer loadingTimer = new Timer(); TimerTask loadingTask = new TimerTask() { public void run() { // set the progress bar progressGaugeField.setValue(DataManager.getDataLoaded()); // for repainting the screen invalidate(); } }; loadingTimer.scheduleAtFixedRate(loadingTask, 500, 500); } Does anyone know how to solve my problem of moving seamlessly from the login screen to the loading screen to the home screen? Note: once I'm at the home screen I'd like to have it be the only screen on the stack. Thanks!

• Dark screen when wake / Unable to control screen brightness

  - by John

  Running Ubuntu 11.04 on Lenovo ThinkPad with an Nvida graphics card. The unit goes to sleep when the lid is shut. (The unit goes to suspend mode (not to disk/hibernate), AC gets turned off, running on battery) Upon lid-open sometimes the screen is almost too dark to read. I'm really not sure of the exact cause, (very low batt??). The only fix is a reboot. The screen brightness buttons have never worked in Ubuntu. I have messed w/ the power management preferences. No change. At one point I messed w/ the gnome settings. No change. I have tried a few cmds: echo 9>/sys/class/backlight/acpi_video0/brightness setpci -s 00:02.0 F4.B=10 xgamma -gamma .75 None of these help. Most have zero effect. I think it is and acpi thing, but that is just a guess. I'm out of idea's, and looking for suggestions. Thanks

• Screen doesn't turn back on after resume on a Lenovo Thinkpad T420

  - by Wojtek

  Every time I suspend my notebook (Lenovo Thinkpad T420 - Intel HD graphic card) on Oneiric Ocelot 11.10 and turn it back on, the screen is black. The backlight is on and the system itself loads fine, but the display somehow doesn't get back. The first time after a fresh reboot the screen isn't black, it is mostly white/light-gray and it looks a bit like a distorted image. The pixels fade in until it gets almost completely light-gray. I've got a workaround for this: I switch to the first terminal (CTRL+ALT+F1) and back to X (CTRL+ALT+F7). In most cases that helps. Sometimes, when there's still a problem, I log in on the first terminal and run "unity --reset". Then go back to X - this helps always. I can tell that the system comes back, because I can log in with my fingerprint reader (or wait a bit and put in the password) "blindly", then do the workaround - I am logged in after the screen comes back. So it's only the display that is not working. Any help or advice where to look would be appreciated.

• How to take a partial screen capture using Ruby?

  - by Jason

  Hi, I need to run a ruby client that wakes up every 10 minutes, takes a screen-shot (ss) of a users screen, crops part of the (ss) out and use's OCR to check for a matching word....its basically a program to make sure remote employees are actually working by checking that they have a specific application open & the case numbers shown change. Not sure where to even start when it comes to taking a screen-shot and cropping it, has anyone done any kind of screen capture work using Ruby? The app will run on OSX using Ruby 1.9 Thanks!

• GNU screen multiuser mode is broken in OS X 10.6 (Snow Leopard)

  - by schustafa

  I'm using GNU screen for remote pair programming. Let's call the local account for the remote user 'pairpair'. I have the following lines in my .screenrc: multiuser on acladd pairpair I have run sudo chmod u+s /usr/bin/screen. However, when the remote user tries to connect to my screen with the command screen -r [my_account_name]/[pid_of_screen] I receive the following message: Attach attempt with bad pid(xxx) The pid listed in the error message matches the pid of the screen process run by the remote user. The remote user's screen process hangs; my screen session continues happily along after the error message disappears. I've tried using both the built-in screen (at /usr/bin/screen) and the screen available from MacPorts, but I get the same error in both cases. This worked on OS X 10.5 (Leopard). I've googled around for the error message, but most of the hits relate to some BSD bug from 2003 or so (which was fixed). Has anyone else seen this behavior? Does anyone have any idea how to make multiuser support in screen work in SL?

• Replay UDP Packet Capture

  I have a UDP packet capture which was streamed from Port1 on IP1 to Port2 on IP2 on network N1. I need to replay these packets on another network N2 from Port3 on IP3 to Port4 on IP4. I need to know what software to use in order to do this and how I would go about replaying these packets so that I can detect/capture them again in N2. So far, I've tried strictly replaying these packets using a program called Colasoft Packet Player, with little luck. I'd appreciate any help on this. Thank you in advance
